Avherald report that they were on their third approach - having already gone around twice.
If this is correct you'd not imagine they'd be caught out by the g/a, nor would you imagine they'd so completely cock up their intercept of the LOC. An even marginally capable crew should be applying lessons learned and getting it right, not getting worse!
If things had been going wrong for the previous two approaches such inexperienced pilot could well have been in a state of near panic by the third. I daresay the CVR will reveal a great deal.
